Access specific link from dynamically build FlexTable

Hello,

I have to implement a messaging system for my application. I want all my conversations to be visible and the user should select one of those to open.

I'm creating a FlexTable from a List of Conversations returned to me via RPC.

My ideea to select one conversation of all available was to link the subject column with a normal servlet getting the id as a parameter.

But the ideea is I do not want to open another page to display the conversation. I want to display it on the same page. I wan't to clear the existing widget and create a new one with all the messages in the selected conversation.

How can I do that ? Link to GWT what was clicked, in order for it to clear the current widget and create a new one...

Or is there a better idea ? Like can it be done through RPC ?

Thanks in advance,

Andrei

DBGetAllConversationsAsync rpc = (DBGetAllConversationsAsync) GWT.create(DBGetAllConversations.class);

ServiceDefTarget tar = (ServiceDefTarget) rpc;

String moduleURL = GWT.getModuleBaseURL() + "DBGetAllConversationsImpl";

tar.setServiceEntryPoint(moduleURL);

rpc.getAllMessages(userInfo, new AsyncCallback<List<Conversation>>() {

@Override

public void onSuccess(List<Conversation> result) {

DOM.getElementById("loading").getStyle().setDisplay(Display.NONE);

int start = 1;

for (Conversation conversation : result) {

int id = conversation.getId();

flexTable.setHTML(start, 0, String.valueOf(id));

flexTable.setHTML(start, 1, conversation.getDate());

String username = userInfo.getUsername();

String source = conversation.getSource();

String destination = conversation.getDestination();

flexTable.setHTML(start, 2, source.equals(username) ? destination : source);

flexTable.setHTML(start, 3,

"<a href=\"" + GWT.getModuleBaseURL() + "viewConversation?id=" + id + "\">" + conversation.getSubject() + "</a>");

flexTable.setHTML(start, 4, "0");

flexTable.setHTML(start, 5, "Unread");

start++;

}

}

@Override

public void onFailure(Throwable caught) {

...

}

});
